As to internal sounds.
[I]t's [...] like a mixture of MANY wind, rain and distant thunder samples all mixed together.
Please do make a recording of this. I'm very interested to hear it for myself. I'm especially interested to hear these unusual differences that seem to be caused by enabling or disabling certain options that, to my knowledge, shouldn't have any such effect.
I discovered that this mod includes GunGeneric.class, of which I have my own modded version. I moved mine farther up the mods list to give it primacy, and now the issue of cockpit sounds going much quieter while firing guns has ceased.
I think I might know what's causing that. Expect it to possibly be fixed in the next version.
I report that these files are missing:
"Cannot open audio file samples/MotorsPiston/Sakae/starter_s.wav"
"Cannot open audio file samples/MotorsPiston/R2800/starter_s.wav"
Thanks for the report. This will be fixed in the next update.
during flak explosions the internal and external sounds of the aircraft are significantly attenuated
This seems to be another strange effect that I can't reproduce.
Fortunately, I do have a very good idea of how to fix it: go into the folder "! Next Generation Unified Sound Mod/presets/sounds" and find the file "explode.zenitka.prs". In that file, decrease the number listed under [spl] to something between 100 and 115.
I just hate when sound mode start meddling with base classes
Changing base classes is very important to how this mod works, and is the cornerstone of all of its new features. Without those base class modifications, this mod might as well not exist at all.
